Question

10.
In the given figure, where AD is perpendicular to BC, The value of x and y are
(A) X= 70°, y = 37°
(B) x= 37º, y = 70°
(C) x+y=117°
(D) x-y=100
​

Answer 1

Answer:

give photo of figure first

Answer 2

In given figure,

(i) AB=AC

(ii) BD=CD

then,

∠ABD=∠ACD Or ∠BDC=∠BAC (diagonally opposite angles are equal)

∠BDC=∠ADB+∠ADC

∠BAC=∠BAD+∠CAD

So y+70=x+37

Only option A satisfies above eqaution

Then x=70 or y=37

Option (a) will be the correct answer.
